Be` it known that I, BENJAMIN B. WEBSTER, of

`East Hni'erhill, of the county jot' Essex and State of Massachusetts, have invented :i new und useful Implement for turning the `edge'ot' n ShoeumkersBniiing-Knife or that o t'n. Currier-s Scraper; and I do herebydeelztrethe saune to be fully described as follows, reference being hud to the accompanying drun-v` tending from it, such being to cna-ble t-he port A to be held to u. bench by inserting the tenen` in :t mortis@ made therein. l I

.'lheimplement further consists of n steel roller or pin, B, set obliquely` in the piece A, and with -respeot to its series ofA slots or kerfs, in manner, as represented in the drmvings In using :the implement vthe knifewhose edge is te be turned is first to be leid on the lest or most oblique slot or korf and drawn lengthwise through it with`the cutting-edge of the knife against and pressed firmly down upon the pin, after which the knife in the sume manner should be introduced into and drawn through each of the other slits' or kerl's. The cutting-edge` will then be found tobzwe been bent down iuto or about et :t right angle with the rest of the blade, or

will be turned in anmuuer well known to curriers or shoemnkers.

With this little implement n workmen cnn e'ect the turning of the edge of his bnfing-knif'e or scraper, not only in very much less time, but in :t far better manner than he can by the common method of accomplishing' such by n hurnisher or tool, es usually heretofore employed. j l

Icla-im es my invention Y V The knife-edge-turning implement as composed of the slitted bloc-k. A and the steel roller or pin B, con` sti-noted nndnrranged substantially in manner end to operate es hereinbefore explained. l
